This paper describes a straightforward methodology for ultra low power design of a radiofrequency building block in CMOS technology. This design methodology is based on two parameters: First, the inversion coefficient of the transistor and the extracted equations from the radiofrequency circuits. Second, an optimum tradeoff between the performance key parameters such power consumption, gain, no...
This paper presents a high power gain (S21) and low Noise Figure (NF) 3.1-10.6 GHz common gate (CG) CMOS ultra wideband (UWB) low noise amplifier (LNA) using active gm-boosted technology, T-match input network, self-body-bias, current reused and noise cancelling technique. Wideband input impedance matching was achieved by using the proposed T-match input network to improve the input matching at...
This paper presents an investigation of noise figure optimization techniques for a 915 MHz CMOS Low Noise Amplifier (LNA). The research’s goal is to evaluate the trade off between fully and partially integrated solutions for 915 MHz CMOS LNA. The analysis considers an inductively source-degenerated cascode topology, which is capable of achieving simultaneous noise and input match, with narrow b...
This paper presents a Sub-mW differential Common-Gate Low Noise Amplifier (CGLNA) for ZigBee standard. The circuit takes the advantage of shunt feedback and Dual Capacitive Cross Coupling (DCCC) to reduce power consumption and the bandwidth extension capacitors to support 2.4 GHz ISM band. An amplifier employing these techniques has been designed and simulated in 0.18 mm TSMC CMOS technology. T...
General conditions for minimizing the noise figure of any linear two-port are reviewed before considering the specific case of a MOSFET low-noise amplifier (LNA). It is shown that the minimum noise figure cannot be obtained over an arbitrarily large bandwidth with networks of low order. For narrowband operation, however, one may construct simple amplifiers whose noise figure and power gain are ...
The first stage of a receiver is typically an LNA (Low Noise Amplifier) which needs to provide sufficient gain while introducing as little noise as possible. The classical noise optimization technique for LNA design presumes that a device is given with fixed characteristics, and thus offers no explicit guidance on how to best exercise the IC designer’s freedom in tailoring device geometries [1]...
This article presents a low-power fully-differential 3.5GHz wideband complementary metal oxide semiconductor (CMOS) lownoise amplifier (LNA) based on the LC-ladder match network approach. To have low power consumption and high power gain, two commonsource stages are cascaded for reusing the bias current. To have wideband low noise figure, the gate width of the input transistor is determined fro...
Due to an increasing demand for simultaneous global roaming and all-in-one wireless phones, the interest in the development of the multi-standard transceivers has been increased. In the receiver front end, the performance of Low Noise Amplifier (LNA) decides overall receiver sensitivity and hence its design plays a crucial role. In this paper, an active inductor based tunable two-stage LNA empl...
